Title: Device for combustion air supply controlling
IPC: F23N1/08
Filed: 1989-04-26
Granted: 1993-02-10
Abstract: According to a method of controlling the supply of combustion air to combustion of a fuel-gas/combustion air mixture, which serves to heat a flowing fluid medium, in particular water, the combustion air throughput is controlled depending on the throughput of the medium to be heated. A device which is suitable for carrying out this method comprises a heat exchanger (8) fed via a water supply pipe (9), and a gas burner (1) which is assigned to this heat exchanger (8) and to which combustion air is supplied via a combustion air guide (2) by means of a blower (3, 4) and fuel gas is supplied via a gas nozzle (5). In the water supply pipe (9) or in the tap line (10) connected to the heat exchanger (8), a water throughput measuring device (14 - 19) is arranged and controls the combustion air throughput as well as - via a control valve (7) - the fuel-gas throughput to the burner (1). <IMAGE>

Abstract: A method for determining the relative quantities of all cholesterol-containing lipoproteins in body fluids by fractionating the lipoproteins in an aliquot of the body fluid by electrophoresis on a support matrix and subsequently detecting them by an enzymatic treatment which comprises an incubation of the support material with cholesterol esterase and cholesterol dehydrogenase and leads to the formation of a detectable complex, and determining the relative quantities of the various lipoprotein classes, where the electrophoresis is carried out on a thin-layer matrix. The method makes it possible to determine HDL-, LDL-, VLDL- and LP (X)-cholesterol simultaneously in body fluids with high precision and at low concentrations. The electrophoresed thin-layer matrices obtained by the method according to the invention are, furthermore, easy to handle and store.

Title: Bipolar ram having state dependent write current
Inventor: HASHEMI A DAVID
IPC: G11C11/414
Filed: 1989-02-13
Granted: 1994-03-23
Abstract: A bipolar RAM (50) having improved read and write cycle times. During a write operation, the state of a selected memory cell (76) is sensed by read/write current controller circuits (90 and 91). A high write current is selected if the data to be written requires a shift of the memory state of the memory cell (76), and a low write current is selected if the data to be written corresponds to the present memory state of the memory cell (76). This improves the write cycle time by reducing saturation of the memory cell (76). If a long write signal is impressed on the RAM (50), the read/write current controller circuit (90 and 91) terminates the high level write current after the memory cell (76) has shifted its memory state. When a memory cell is being selected for a read or write operation, the write current select circuit (142) discharges the bit line attached to the low voltage side of the selected memory cell, improving the read cycle time.

Date Oct. 4, 1990.The measuring device is incorporated in a projection of the casing. Its auxiliary electrode forms the high-voltage capacitor of a capacitive voltage divider together with the internal conductor, and is connected with the casing via a low-voltage capacitor. The measurement connection emerges from the projection in gas-tight manner, and is connected to a display or measuring device. In order to be able to detect high-frequency compensation operations, also, the low-voltage capacitor consists of two nested cones with a solid dielectric. A terminal resistor which is connected to the internal conductor of a gas-tight coaxial connector is arranged in the inside cone. The terminal resistor is adapted to the characteristic impedance of the coaxial connector and that of the measurement connection. The measuring device with the auxiliary electrode can be inserted into tubular gas connections in the casing of a high-voltage conductor, especially in compressed gas-insulated, encased high-voltage switch conductors.

Abstract: In a roof (1) for bungalows, having sloping insulating slabs (11, 11', 11'' ...) made of an insulating material, which are bonded next to one another on the roof surface (2) and to which a seal (12) consisting of overlapping sealing webs (15) is applied, a hard roof covering (31) is welded to the seal (12) of the sloping insulating slabs (11, 11', 11'' ...). This design provides a roof (1) which not only has a low roof inclination, but also affords the advantages of a steep roof. Expensive roof drains and also turn-ups at the edge of the roof are no longer necessary; the rainwater can be carried away rather in a gutter (35). In addition, the seal (12) is not excessively strained by insolation, temperature fluctuations and plant growth, and consequently has a long life. <IMAGE>

Abstract: A synchronizing circuit to synchronize a digital input signal (DIN) with a clock signal (CK1) includes a detection circuit (DC) which checks if a present (SA) sample of a clock signal (CK3) being synchronized with the digital input signal, is equal to the previous (SB) sample, both samples being taken at an interval equal to the period (T) of the clock signal synchronized with the output signal. When the samples differ, the detection circuit generates a phase adjustment signal (CLR), which triggers a phase adjustment circuit (PAC) to ensure a return to synchronism by phase shifting the signal (ES) controlling the sampling of the digital input signal. <IMAGE>

Abstract: In the integrated circuit, two first transistors (Q1, Q2) are arranged in series with one another between connections for a first (VDD) supply potential and a second supply potential (VSS). These transistors are of mutually complementary channel type. Furthermore, a serial network (N) is arranged between the two connections. It contains at least two second transistors (Q3, Q4) and at least one element (R1) which exhibits a voltage drop in operation. The second transistors (Q3, Q4) are of mutually complementary channel type. The serial network (N) acts as voltage divider circuit. The sources of the transistors (Q1, Q3) of one channel type are connected to the connection for the first supply potential (VDD). The sources of the transistors (Q2, Q4) of the other channel type are connected to the connection for the second supply potential (VSS). The drain connections of the two first transistors (Q1, Q2) form a first circuit node (N1), at which the reset signal (OUT) is produced in operation. The first circuit node (N1) is connected to the gate of the second transistor (Q4) of the other channel type. The gates of the first transistor (Q1) and of the second transistor (Q3) of in each case one channel type are both connected to the drain of the second transistor (Q3) of one channel type of the serial network (N), forming a second circuit node (N2) which, in turn, is connected to the gate of the first transistor (Q2) of the other channel type.
